When assessing a community to determine its health needs, which data would be most useful?
- A. Demographic data
- B. Health behavior data
- C. Environmental data
- D. Morbidity and mortality data
Correct Answer: D
Rationale: The correct answer is D: Morbidity and mortality data. This data provides direct information on the health status of the community by indicating the prevalence of diseases and deaths. It helps identify major health issues, prioritize interventions, and allocate resources effectively. Demographic data (A) provides information on population characteristics but does not directly reflect health needs. Health behavior data (B) offers insights into lifestyle choices but may not capture underlying health conditions. Environmental data (C) focuses on external factors impacting health, which are important but not as direct in indicating community health needs as morbidity and mortality data.

Which of the following is an indication for tracheostomy?
- A. Drainage of pleural effusion
- B. Hemorrhage
- C. Infections
- D. Acute respiratory failure
Correct Answer: D
Rationale: The correct answer is D: Acute respiratory failure. Tracheostomy is indicated in cases of severe respiratory compromise when the upper airway is obstructed or when long-term mechanical ventilation is needed. It ensures a patent airway and facilitates weaning from a ventilator. Choices A, B, and C are incorrect as drainage of pleural effusion, hemorrhage, and infections do not typically require a tracheostomy for management.
What is a primary objective of public health?
- A. Lowering the prevalence of chronic diseases
- B. Eliminating health disparities among populations
- C. Delivering health education
- D. Extending life expectancy
Correct Answer: B
Rationale: The correct answer is B: Eliminating health disparities among populations. This is the primary objective of public health as it focuses on ensuring that all individuals have equal access to healthcare and resources to achieve optimal health outcomes. By addressing disparities, public health aims to promote health equity and reduce inequalities in health status. Lowering chronic diseases (A) and extending life expectancy (D) are important goals but not the primary objective. Delivering health education (C) is a strategy within public health but not the main objective.
What is the most effective method for preventing the spread of disease?
- A. Hand hygiene
- B. Vaccination
- C. Quarantine
- D. Use of personal protective equipment
Correct Answer: A
Rationale: The correct answer is A: Hand hygiene. Proper hand hygiene, including washing hands with soap and water or using hand sanitizer, is the most effective method for preventing the spread of disease. This is because hands can easily pick up and transfer germs from surfaces to our bodies. Regular handwashing can remove these germs and reduce the risk of infection.
Summary of other choices:
B: Vaccination is important in preventing certain diseases but may not be as effective in controlling the immediate spread of a disease outbreak.
C: Quarantine can help contain the spread of disease in specific situations but may not be as universally applicable as hand hygiene.
D: Use of personal protective equipment is crucial in certain settings, but it is not as practical or accessible for the general population compared to practicing good hand hygiene.
Why is cultural competence important in community health nursing?
- A. It helps nurses provide care that is respectful and responsive to the health beliefs and practices of diverse patients.
- B. It mandates all health care providers to undergo cultural training.
- C. It ensures that nurses are knowledgeable about different medical practices.
- D. It prevents nurses from encountering cultural misunderstandings.
Correct Answer: A
Rationale: The correct answer is A because cultural competence in community health nursing enables nurses to provide care that respects and responds to the health beliefs and practices of diverse patients. This is important for building trust, improving communication, and enhancing patient outcomes. Choice B is incorrect because cultural training is not mandatory for all healthcare providers. Choice C is incorrect because cultural competence goes beyond medical practices to encompass understanding and respecting patients' cultural backgrounds. Choice D is incorrect because cultural competence does not prevent misunderstandings, but rather helps nurses navigate and address them effectively.
Which is an example of a secondary prevention strategy?
- A. Administering immunizations to prevent disease
- B. Conducting health screenings to detect early signs of disease
- C. Providing rehabilitation services to prevent complications
- D. Educating the public about healthy lifestyle choices
Correct Answer: B
Rationale: Step-by-step rationale:
1. Secondary prevention aims to detect and treat diseases at an early stage.
2. Health screenings help identify early signs of disease before symptoms appear.
3. Early detection allows for prompt intervention to prevent disease progression.
4. Administering immunizations (A) is an example of primary prevention.
5. Providing rehabilitation services (C) is an example of tertiary prevention.
6. Educating the public (D) focuses on promoting healthy behaviors, also a primary prevention strategy.
Summary:
Option B is correct as it aligns with the goal of secondary prevention by detecting diseases early. Options A, C, and D are incorrect as they represent primary prevention, tertiary prevention, and health promotion strategies, respectively.
